The article shows that the type and concentration of inorganic salt can be translated into the structure of the bulk phase and the performance properties of ecological all-purpose cleaners (APC). A base APC formulation was developed. Thereafter, two types of salt (sodium chloride and magnesium chloride) were added at various concentrations to obtain different structures in the bulk phase. The salt addition resulted in the formation of spherical micelles and-upon addition of more electrolyte-of aggregates having a lamellar structure. The formulations had constant viscosities (ab. 500 mPa·s), comparable to those of commercial products. Essential physical-chemical and performance properties of the four formulations varying in salt types and concentrations were evaluated. It was found that the addition of magnesium salt resulted in more favorable characteristics due to the surface activity of the formulations, which translated into adequately high wettability of the investigated hydrophobic surfaces, and their ability to emulsify fat. A decreasing relationship was observed in foaming properties: higher salt concentrations lead to worse foaming properties and foam stability of the solutions. For the magnesium chloride composition, the effect was significantly more pronounced, as compared to the sodium chloride-based formulations. As far as safety of use is concerned, the formulations in which magnesium salt was used caused a much lesser irritation compared with the other investigated formulations. The zein value was observed to decrease with increasing concentrations of the given type of salt in the composition.
该文章表明，无机盐的类型和浓度可以转化为本体相结构以及生态通用清洁剂（APC）的性能特性。开发了一种基础APC配方。此后，添加了两种不同浓度的盐（氯化钠和氯化镁），以在本体相中获得不同结构。加盐导致形成球形胶束，并且在添加更多电解质时形成具有层状结构的聚集体。这些配方具有恒定的粘度（约500 mPa·s），与市售产品相当。评估了四种盐类型和浓度不同的配方的基本物理化学和性能特性。发现添加镁盐由于配方的表面活性而产生了更有利的特性，这转化为所研究的疏水表面具有足够高的润湿性以及它们乳化脂肪的能力。在发泡性能方面观察到一种递减关系：较高的盐浓度导致溶液的发泡性能和泡沫稳定性变差。与基于氯化钠的配方相比，对于氯化镁组合物，这种效果明显更显著。就使用安全性而言，与其他研究的配方相比，使用镁盐的配方引起的刺激要小得多。观察到玉米醇溶蛋白值随组合物中给定类型盐浓度的增加而降低。
